Hello Community.
We just Upgraded TrueNAS (on physical Server HP DL380 G10) from BLUEFIN over COBIA to DRAGONFISH 24.04.2 (actually 24.04.2.2) and since then we have strange situation with NFS performance. NFS is only used from one Server and it works fine for a while, then CPU Wait starts raisng (sometimes up to 99 %) and nothing works, then again after a while CPU Wait comes to normal state (< 1 %) and everything works fine.
I already found the topic about NFS hung after upgrade and we had the ame issue. I deactivated NFS4 and NFSD do not hang but makes this strange things.
Do anybody have an idea or had the same issue ?
Thanks in advance and best greetings
Joerg
